Energy-efficient glass — is it worth installing?

The issue of saving energy is a very topical one. For this reason, many people are looking to replace old wooden windows with modern PVC structures that keep the home warm, reduce noise, and help save on heating bills.

More and more often we hear about energy-efficient glass and its effect in the energy-saving process. What does energy-efficient glass actually mean, what is the difference between a window of this type and one with ordinary characteristics, and is it worth investing in such glass or not?

We will answer the most popular questions about it and share our own experience in working with energy-saving glass. So, let's get started!

How does the window save energy?

Did you know that energy-efficient glass is 4.6 times warmer than ordinary glass?

Saving energy = reducing energy costs. As far as windows are concerned, saving energy means savings on heating and air conditioning of the room in which this type of glass is installed.

It has been shown that 30-37% of heat is lost precisely through the glass. Money for heating flows out through „cold” windows that do not have sufficient thermal insulation.

An energy-efficient window is an insulated glass unit in whose internal cavity there is an inert gas (Argon), while a layer that reflects heat is applied to the inner surface of the glass.

Thanks to the special formula we use in production: 4 mm Low E + Argon Gas + 4 mm + Argon Gas + 4 mm 4 Seasons, you get a truly warm glass.

When do we replace a double-glazed window with an energy-saving one?

Two scenarios are possible here:

1. The old window needs to be replaced in any case. High-quality insulated glass units, with several air chambers, will achieve an acceptable result in terms of resistance to heat transfer. To do this, the opening must have enough depth to install a wide profile. But the installation work will be complicated by the bulk of the whole structure and the great weight of the insulated glass unit.

2.When the PVC structures are already installed, are no more than 2 years old, but the windows sweat and it is cold in winter, two options are possible. It can help to improve the room's ventilation, correct mistakes in the finishing of the openings, change the location of the heating radiators or, finally, replace them with high-quality windows with a large number of chambers. On the other hand, instead of replacing the windows, it is easier to swap a window with a simple insulated glass unit for an energy-saving one. This helps you save a significant amount, and the effect will be the same. It only remains to eliminate other causes of fogging.

Advantages of energy-efficient glass

Now imagine that 30-35% of the heat in the house escapes through the windows; we make up for the heat loss with stronger heating or electric heaters, which entails additional financial costs. Have you ever wondered how high these costs are?

So, the main advantages of energy-efficient insulated glass units are:

• a high rate of thermal insulation thanks to reflecting thermal radiation back into the room;
• significant savings on heating the spaces;
• no condensation on the inner surface of the window (the glass temperature is higher, the air in the room does not pass the dew point when it comes into contact with the glass — the moisture does not condense);
• noise reduction from the outside thanks to the 3 panes of glass.

What else influences the energy efficiency of windows?

It is directly affected by the profiles, the hardware, and the quality of installation. If you fall short on at least one of these points, the windows will retain heat less well.

Customer reviews about energy-efficient glass:

How do we tell ordinary glass from energy-efficient glass?

Lifehack:

There is a proven popular method that lets you tell energy-efficient double-glazed windows from ordinary ones. To do this, you simply need to bring a lighter with a lit flame close to the glass. Ordinary types of double-glazed windows will reflect the flame in yellow, while energy-saving glass will show a red light in the reflection. This verification method can be used as an auxiliary one when you want to choose energy-saving windows and make sure of their properties before purchase.

In conclusion

We hope that, after reading our material, you will understand what energy-saving windows are. In conclusion, we note that installing them helps save on heating bills and significantly reduces the noise level in residential spaces.

The main thing to remember is the rule: a miser pays twice. Seek services from trustworthy companies and not from fly-by-night ones that offer to install insulated glass units cheaply!

We believe there is no longer any doubt about the advantages of energy-efficient windows over conventional ones. When choosing new windows you will make the right decision, and if you still need a consultation, our manager Dan will gladly help you!
